The present invention relates to a grease feed pump device for transferring grease in a grease drum to a feed tank in a paper feeding equipment. The grease remaining in the lower part of the drum and the wall after grease supply is collected and filled by the scraper at the pump inlet side. This is to prevent grease waste by completely removing grease without remaining.

In the process of transferring the drum from the drum to the feeding tank to the feeding equipment supplied to the driving unit of each roll, the remaining grease is excessively consumed in the performance equipment used in order to remove grease remaining in the drum. There is an urgent need for a grease feed pump device to solve this problem.

The grease filling pump used in the related art has only a pump inlet line 101 in the drum 100, as shown in FIG. 4, so that the grease 200 having a high viscosity at the time of pumping remains large in the both corners of the bottom. It is done.

Therefore, the grease 200 remaining on the wall and the floor is wasted a lot, and the residual grease 200 is usually disposed of in a state where it remains in the empty drum 100, thereby causing environmental problems and problems in reprocessing the drum 100. When the drum 100 is replaced, the pump 102 is heavy, and handling is not easy, as well as a load on the work and there is a problem that a risk of safety accidents is included.

Therefore, the present invention has been invented to solve the above problems, by integrating the pump integrally with the grease by the load to prevent the pump efficiency decrease due to air inflow and scrape off the residual grease on the wall and to the rotation of the scraper It is to provide a grease feed pump device by collecting the grease in the lower portion by the pump inlet side to completely remove the desired pumping and residual grease.

The grease feed pump device will be described in detail with reference to the accompanying drawings.

The bottom of the inlet line 7 is assembled to the bearing housing 2 with the pinion 2a formed at the center of the air tube 1, and the check valve housing 4 with the grooves 4a formed at the bottom and side. The pinion (3a) is formed at the upper end, the scraper housing (3) formed in the body penetrates through the scraper housing (3) and assembled into the screw type at the lower end of the entry line (7), the discharge line (10) and the entry line in the cylinder (9) (7) is assembled and connected to the discharge line 10, the check valve housing 11 is connected, the air cylinder 12 is connected to one side of the cylinder (9) by the shaft 16 is installed air cylinder ( 12, one side of the shaft 16 to enter the interior of the packing 18, the piston 17 and the spring 20 is installed in sequence, and the other side of the shaft 16 entering the cylinder 9 is the packing (18a) and The piston 17a was installed and the rack 19a was attached to the lower end of the rack shaft 19 formed integrally with the shaft 16. On the other hand, the direction change valve with the air supply line 36 and the silencer 38 installed on the upper end of the air cylinder 12 with the direction switching wall actuating bar 26 on the front end having the solenoid valve 37 installed. (13) was installed, and limit bars 26a and 26b were formed on the direction changeover operation bars 26 so as to be grounded with the plate 39 formed integrally with the shaft 16.

In addition, the check valve housing (4) (11) of the present invention was formed by the reinforcement portion (4b) (11b) to seat the check ball (5) (5a), respectively.

Referring to the effects of the present invention configured as described above are as follows.

According to the present invention, as shown in FIG. 4, the bearing housing 2 is assembled to the entry line 7, and the check valve housing 4 penetrates through the scraper housing 3 and screwed to the lower end of the entry line 7. Are assembled.

In addition, the cylinder 9 and the discharge line 10 and the entry line 7 are assembled and assembled, and the check valve housing 11 is connected to the discharge line 10.

An air cylinder 12 is assembled to the cylinder 9 by the shaft 16. The pump thus assembled is mounted to the grease drum 100.

Therefore, in the present invention, the air is supplied to the direction change side 13 during the initial operation, and air is introduced into the air cylinder 12 through the air hole and the stopper block 21 to push the shaft 16. At this time, the 0-ring 32 is inserted in order to prevent the leakage of air when assembling the turning side 13 and the stopper block 21.

On the other hand, when the shaft 16 is moved by the air inlet to the air cylinder 12, the spring 20 is compressed, the piston 17a is pushed, the cylinder 9 stroke is shortened, and the grease 200 in the cylinder 9 is reduced. Is discharged through the discharge line 10 and the check valve housing (11). At this time, the check ball (5) prevents the check valve housing (4) from being backed off, the bar 29 and the rack shaft (19) moves along the shaft (16) as well, and the rack (19a) to the pinion (2a) It is bent by this and crosses the mountain of the pinion 2a. In addition, the bar 29 moves to contact the limit bar 26a of the direction change valve operation bar 26 and pushes the limit bar 26a to operate the internal splice of the direction change valve 13 to operate the air inlet hole. Air at 35 is shut off and air in air cylinder 12 is vented out through air vent hole 31 and shaft 16 is returned by spring 20. At this time, the bearing housing 2 rotates only the pinion (2a). In addition, in the present invention, when the shaft 16 is moved, the bar 29 moves the limit bar 26b of the direction change valve operating bar 26 by the limit bar 26a. The air vent hole 31 is closed and air flows back into the air cylinder 12 through the air inlet hole 35. In this way it is continuously repeated.

Therefore, when only the residual grease 200 remains in the drum 100 of the present invention, as shown in FIG. 3 (a), the pump is lowered to the lower part of the drum 100, and the check valve housing 4 is bottomed. And the scraper 33 is pushed down than the check valve housing 4, and the scraper 33 is moved upward to contact the pinion 3a and the rack 34. In addition, the pump continues to operate and the scraper 33 rotates as the rack 19a and the pinion 2a come into contact with each other so that the residual grease 200 at the bottom of the drum 100 is drilled through the check valve housing 4. Transferred. Once again, when the grease 200 is normally pumped, as shown in FIG. 3 (a), the rack 34 and the pinion 3a are separated, so that the pinion 2a and the rack ( Only rotate 34). At this time, the pump is lowered by the decrease amount of the grease 200 while the grease 200 of the wall is lowered by the air tube 1 and remains at the bottom as shown in FIG. If only the grease 200 remains, the pump stops descending by the check valve housing 4 and instead the scraper 33 is lowered than the check valve housing 4 and moved upward, while the pinion 3a and the rack ( As the 34 is engaged and rotated, the residual grease 200 is introduced into the pump by the scraper 33 through the groove 4a drilled into the pump inlet, that is, the check valve housing 4, so that the residual grease 200 is removed. On the other hand, when the cylinder 9 is compressed, the upper check valve 11 is opened and the lower check valve 4 is closed. On the contrary, when the cylinder 9 is returned by the force of the spring in the air cylinder 12, a vacuum is generated in the cylinder 9 so that the grease 200 is introduced while the check valve 4 is opened and the check valve 11 is closed. Reverse flow is prevented. The check ball stoppers (6) and (6a) are installed to prevent the check balls (5) and (5a) from being lost when the check valves (4) and (11) are operated. (12) was installed to secure the balance bar (15) was installed for the purpose of maintaining the balance of the pump when the pump moves to the lower drum and the air line (40) between the drum and 100 when the drum 100 is replaced It was installed to dismantle the pump in the drum (100) by dismantling the vacuum force and letting in air.

When the solenoid valve 37 receives the signal of grease supply at bys' during the initial operation, the solenoid valve 37 is opened and air ≒ 6kg㎠ (* AIR pressure may be changed depending on conditions). ) Is supplied and the air flows into the air cylinder 12 along the flow path of the direction changeover side 13 to expand the pressure between the packing 18 so that the piston 17 moves in the direction of arrow ⓔ and the shaft 16 also The piston 17a in the direction of arrow ⓐ also moves in the direction of arrow ⓖ. At this time, the cylinder 9 has its volume condensed, and the grease inside the cylinder 9 is increased in pressure so that the check ball 5 at the bottom is closed and the check ball 5 a at the top is open. Discharged.

At this time, the rack shaft 19 provided on the shaft 16 and the bar 29 also move in the direction of arrow ⓐ, so that the bar 29 is a limit bar provided at the tip of the directional telephone operating bar 26. By moving to 26a) and pushing the limit bar 26a, the flow path of the direction changeover side 13 is changed.

In addition, the rack shaft 19 also moves together, the rack 19a connected thereto does not move the pinion (2a) is over the pinion (2a).

On the contrary, when the flow path of the direction telephone side 13 is changed and the air of the air cylinder 12 is discharged to the silencer 38, the air pressure of the air cylinder 12 is reduced and the piston 17 is driven by the force of the spring 200. When you return everything is back. At this time, as the volume of the cylinder 9 increases, the internal pressure changes to the vacuum side, the check ball 5a at the top is closed, and the check ball 5 at the bottom is open, and the grease 200 in the drum 100 moves in the direction of arrow ⓙ. Grease is introduced to fill the cylinder (9). When the return is completely completed, the bar 29 pushes the limit bar 26b of the direction changeover operation bar 26 so that the flow path of the direction changeover side 13 is changed to operate again for the first time.

When only the remaining grease 200 remains in the drum 100 during the continuous operation as described above, as shown in FIG. 3 (a) of the accompanying drawing, the scraper 33 touches the lower part of the drum 100 to be raised in the direction of arrow ⓒ so that 34 and the pinion 3a mesh with each other to slowly rotate the rack shaft 19 so that the lower grease enters the groove 4a by the scraper 33. At this time, if the p / p is lowered too much, the scraper 33 receives a lot of load, so the screw is assembled when the check valve housing 4 is assembled.
